Inertia
Slide for every gem. Find somewhere safe to stop.
How to play Inertia
Collect all the gems by sliding the ball. Walls, edges and stop circles halt a slide; touching a mine is fatal, but you can undo it. Play with the original Nickelbar rules and board drawings. Help below the game lists its keyboard and mouse shortcuts. Your current game stays in this browser tab.
- Use the arrows to slide horizontally or vertically.
- Click in a direction or use Y, O, B and M for diagonal slides.
- Collect every gem. Undo a wrong turn with U.
